RE: Flap deployment
Done! Thanks everyone.... should be a lot smoother. It appears totally symetrical on a servo slow setting of about 15 sec. Will fly this weekend.

RE: Flap deployment
i've found that rotating the arm 180 degrees can make a difference when setting servos side by side. something to do with the spline orientation, i was once told.
my only reference is with JR HD215 servo arms. been matching servo arms for years this way. i also generally try to purchase a reversed servo thus bypassing a matchbox. |
RE: Flap deployment
hey, you flying this weekend?
Iwant you to consider doing "career day" at my school; it's a friday in Nov..... a couple 30 minute small classes kids choose electives like "lawyer," "pizza delvery guy," "doctor," "fighter pilot" etc. I'll tell you more later...... they'd dig it |
RE: Flap deployment
Glad you got it sorted out, just an FWIW JR has an odd number of teeth and if one selects the single sided arm you can only get it to install centered one way, which ends up being wrong for one of the flaps servos. You must use the double sided arm and cut off the correct side not used.

RE: Flap deployment
Here's something that y'all might be able to help me with...first, I'm using a JR x9303 TX and an AR9100 RX, and first-time matchbox user. I was setting up the RX channels today in my Skymaster L-39. THRO, RUDD, GEAR are obvious. My plan was to use AUX3 for steering and AUX4 for brakes.
So, I used AILE and AUX2 for R and L aileron servos. Got AILE/AUX2 mated and rigged with no trouble. Next, I put the ELEV into a JR Matchbox, with the right servo in 1/5 and left in 2/6. Followed the directions and got the elevators working and rigged in just a few minutes. So far so good. Last, I plugged the second matchbox into the AUX1 (flap), with the right flap in 1/5 and left in 2/6. And that's when it all went to crap. No matter what I tried, I absolutely could not get those servos in sync. I could not reverse the left flap servo. I tried switching the positions in the matchbox, still AFU. Nothing worked. I could get one flap or the other to work, but not both. After a while I had to just walk away and take a break. I came back, put the ailerons on the matchbox, and got them working in no time. I then mated AUX1 and AUX2, right and left flaps servos plugged in, and with some tweaking of the x9303 they work fine. I was really starting to think the matchbox was defective until the idea hit me to put the ailerons on it. So, it probably matters not one bit whether the it's the flaps or the ailerons on the matchbox, although for me I'm used to having AILE and AUX2 mated. And, since the ailerons get a lot more work than the flaps, it seems power-wise it might be better to have the ailerons on separate RX channels and the flaps on the matchbox. Anyway, long-winded story, but I am totally baffled as to why the matchbox would not work with the flaps. Any ideas? This 'gremlin' is bugging me. |
RE: Flap deployment
i would really try another set of servos. i'm thinking the whole problem is your servos are not matching each other. one may be worn out if they are not new. i have run into this before. i think if eveything is the same on both sides then that leans me towards the servo being the problem. try two different servos is a quick way to eliminate them as suspect.

RE: Flap deployment
That could be. When I put the ailerons on the matchbox they worked just fine.
As far as leads, they have a 24" extension. The servos are Futaba s9155's and they are brand new. What's wierd is that once I mated them on AUX1 and AUX2 and got the TX set, the servos worked fine...except for buzzing at the up/retracted postion. I still need to sort that out. I will say this much, though. This whole mess of sorting these flaps out was almost enough to piss off the Good Humor man! |
RE: Flap deployment
As far as servo reversers go....This, too, is a classic example of getting what you pay for...All of the cheap servo reversers will change the output of your servos with the change of temperature...Take a heat gun to a cheap servo reverser and watch your servo move as the heat changes...
There is one that is a cut above the rest...The Pro Servo Reverser by ElectroDynamics...Heat tested from 10 degrees to 140 degrees with 99.995% stability...And it WON'T cause your servos to jitter either!!!...But at $29.95 they aren't cheap as compared to others.. http://electrodynam.com/rc/EDR-106/index.shtml I'm not a rep but an extremely satisfied customer of Andy's products...
